Mr. Geofroy to Mr. Seward.
Recent advices, brought from Mexico to the government of the Emperor, have apprised him that very grave events, the responsibility for which would fall upon the government of the United States if it neglected to take them into serious consideration, would again be brought about at Matamoras. A great number of federals, after having evacuated Brownsville, have, as it seems, passed the Rio Bravo and put themselves at the disposal of Mr. Cortinas. This chief would also have received a considerable supply of arms and munition, despatched from American territory. If these advices are true, as it seems there is no ground to doubt, there must have been there a violation of neutrality, which of itself alone would give sufficient ground for reclamation on the part of the government of the Emperor. But the life of French subjects has ceased to be respected by the party dominant at Matamoras; two of them, as it seems, had been shot by order of Mr. Cortinas. It will, therefore, be the duty of the government of the Emper to protest the more energetically against the support given in this circumstance to its adversaries.
